To all whom 'itfmay concern.'

Be it known that 1, 'ANTON SCHUERMANN, a resident. of the city of Decatur, county of Macon, and State of Illinois, ha .'e invented a. certain new and useful RollepBearing ,for Self-Closing Liquid Shut-Oils, of which the following is a. specification.

This invention is designed to facilitate the opening of sel--closing coc zs, faucets and the like and it. applies Yto liquid shut-oils in which the, opening motion is produced by r0- tarj motion against inolinedplanesand in which the closing is etl'ected by spring tension.

1 .In devices of this general type where loose balls or. rollers have been employed, there was the objection thatthey often fell out- -when the parts were disconnected and heconie lost. Moreover, if one ball or roller were slightly larger Athan the other or others- (as is almost. invariably thecase, either becauseof their imperfect formation or because of wearijn them or on the track ways) the larger roller sustains the force of the thrust and is liable to become crushed, While the smaller 'roller or rollers often stick in place and cram'p the device and certainly da vnot move simultaneously with the larger. roller nor through the same path. Hence a slightly oblique movement i s, am)lied to (he "valve stem and v'alve', and they wear andthe deviceson leaks. .Final j', the further oli-# jection exists that where the valve stern is connected with and rotated b v the valve handle, the valve itself is ground upon its seatl and wears or becomes loosened from the Stem. These various objections it is' the purpose of the.' present invention to overcome. Y

In the drawings forming part of this specification Figurel is a section through the body of. a self-closing basin cock embodying my improvement; the valve of the cock.lie-' ing` adapted to open against the water pres.'-

''is a plan of the spider and rollers. showing them in the vposition they occupy in' Fig. 2; -Fig.' 8A is an elevation of the oper-v ative/partei the stationary roller-Way shown mais?.

'Referring 'to thedraivings, and more espeeially to Fig. 1, 12 deslgnates the cock lbody Within which movesthevalve stem 13 carrying the valve 14 and within which is l guided a sliding d isk 16 lthat is held by ar-nut 7i) 27 against: a shoulder 'around Athe reduced and threaded upper end 26 ofthe' stem, and 15 is a spring encircling the stem between. said disk and -a fixed part of thebody sofas 'to nomially close the valve. The ca. "01"71'5V bonnetx is screwed ont-o the 'cockvb A as shown and carries within its upper' 'end a' fixed roller-Way S which is a circula-r track' comprising preferably three like undulations Whose apexes are indicated at -9 inFigs, '3.80

and 4. VThe handle 10 is rigid with its shank 5 which passes through a hole in-theetopof the cap and carriesatvits lower end adisk 6 which rests upon but; is disconnected vfrom the upper reduced end 26 vof the valve stem, A85. and said disk has on its upper tace a movable 'roller-way corresponding: with said fixed way and havmgapexe's- 7. Between these tivo ways and upon the'shank 5 is journalcd the nole 2 through a spider 1, here shomi as hav- BQ mg tnree radial pms 4 on which are mounted rollers 3. Xo'rmallvthe latter stand hct'ween the depressions in the ways as seen in Fig. 3, but when 'the shank is turned by the handle the movable Way rotates beneath the rollers and tlie'lat-ter travel at half speedLso that said Way is caused to descend as shownv in Fig. 4, and the disk ti'thus engages the valvestem- ,13 by impingingagainst it and compressing the spring-l5. and opens the' 1.00 valve. 1-\ shouldcr 1.1 on the shank strikes the iop of the cap justliefrore the riillcis reach the :1p1- ves of vthe tracks'. and limits the ro- 't-ation et' the diskso that thc' rollers will notl pass over the apcxes. Obviously he `valve ,N5 can he opened h v turningy the handle citlwr \va v. The useof the spider keeps the rnll'cis equally spaced, prevents their crampingv or bndinf. and cmpleys them.simultaneously soiiat'thc dmvmvard dlrust nlV the disk upon l l thv valve steni'is in n' direct -axial .lint-.hand :nest-cn; and valve. will not cramp.' "The fact' that the disk and ste-mare not connected permits the latter have a straight longitudinal movement and obviates the grinding of the valve upon its seat.

,55' In the construction shown in Fig. 2, 22 is the cock body and 21 vthe cap between which is clamped a fixed disk 16. 24 is the valve mounted on a stem 23 which slides through this disk and is normally closed by a spring i0 25. Here also the fived way 2O is on the cap though it faces upward.

' 17 is the handle whose shank 18 is tubular and cup shaped, and carries within its upper end the movable way 19 which preferably also consists of three undulations having 'apexes corresponding With those numbered 20L on the fixed wav as seen in Fig. 8. In

this Ainstance the valve stem is reduced as at 26 te form a shoulder 28 which -impinges .20A against the cap 21 when the valve has been opened, and-as in the other instance-Just before the rollers 3 on the spider 1 reach th'e apexes of the trac s. The reduced end 26 of the Yvalve stem passes through but is disconnected from'the handle, and carries a nut 27 f at its u per end and entirely above the hanby. connectin dle. T e latter can obviously be turned in either direction .to open the valve, and here again the movable way engages the stem by 3o impinging against its nut 27. As in the other type, the valve will not necearily Xe rotated and therefore will notbe grou d Vupon its seat nor accidentally detached fr om its stem.

opens-1n the opposite direction from the valve in the other. In either case access'can vbe hadto the parts by removing the cap or 4o bonnet, although in Fin'. 2 the nut 27 must first be removed from the stem and then the tubular shank and handle can be lifted oh'. Suitable provision-may be made for remov- "ing-the shank 5 from the cap 8 of Fig. 1, as said shank detachably with either the dis 6 or the handle 10, but this feature forms no part of the present invention. In separating the parts the s ider is readily detachable, and as the r o ers are 5 0. ournaled on the pins 4 they can not become ost accidentally as might be the case if the Were'loose. In F i 1 the rotation of the dis 6 does not rotate t e stem 13, although in its descent it impinge's against the stem and deresses it-in Fig. 2 t e rotation of the tubuar shank 18 does not rotate the stem 23, although in its rise it causes the hidleto iminge against the'nut 27 and rais the stem. ghus in either construction it wo d be pos- `60 sible if thought wise to provide some means for positively preventinv the rotation of the stern, but this feature forms no par-i. 01 the .fpresent invention.

. .W hne the spx-in i's neceary in construc- 5 tions Where the .va vec-loses against the pres- ,tracks, rollers journaled on said -structions where the valve closes with the pressure, as in Fig. 1,1 although I consider vits use preferable. So also the sliding disk 16 might be omitted, or replaced by some other form of guide.
